I think that’s a good way of thinking about a lot of art, or really anything where there isn’t some objective metric for better vs worse. The value is in the story behind it, and a major part of this story is that it was made by the hands o

The true goal of most customer service systems like that is to make you decide it’s not worth the hassle and give up. Viewed from that perspective I think labyrinthine phone systems make a lot more sense.

This does exist, as a combination of a spectrum analyzer and software defined radio. But For the bandwidth you're talking about, esp 6ghz wi-fi, and to get good signal fidelity and fast data decoding, they cost thousands.

I’m working on developing a new kind of flexible linear actuator for robotics and prosthetics. Essentially an artificial muscle. If we can make production economical it’ll make a big difference in how energy efficient and human-like robots

I don’t understand how this works but it’s very cool. I would to be able to feed in a few photos of something like a property viewing or a birthday party and it just churns out photorealistic 3D scenes like this. Makes me wonder about its p

Did you at least get paid for the extra “time” or was it purely going to the company? Makes me wonder how the manager (or anyone else doing a similar thing) justified to themselves that doing this sort of thing was ok, since most people don

Hi Rob, I love the concept. I've played around with it for about 20 minutes now. I use obsidian for almost all my notes and documentation because I like keeping everything as close to plaintext as possible. I also currently use Omnipl

I’ve lived in Sydney most of my life. I suspect that it genuinely is partly because Australia, particularly NSW, did start off as a prison colony, and as a consequence our police force and legislature has always tended towards the conservat

Geopolymer concrete pretty much fits the bill for this. From my layman’s understanding the main reason we don’t use geopolymers instead of Portland cement is because we already have so much infrastructure for Portland cement

The article gives the opinion that this is an entirely negative thing to have happened, and implies that it is bad for consumers. While it’s absolutely bad for Nvidia, I’m not convinced it’s bad for ‘progress’ of GPU/AI etc development

Unfortunately it isn’t that simple. A lot of these lenses are expensive not just due to rarity but from the shear complexity and difficulty in producing them. Some can take literally months of production time. They frequently contain dozens

Great to see some playfulness and whimsy in this architecture. So many architects today only pursue minimalist grey boxes in everything they do. It might be garish when it’s this bold, but I really wish a little more of this kind of thinkin

It’s difficult with helium because the atom is so small that it can effectively penetrate the gaps in the atomic structure of almost any solid material given time. Even solid iridium can have small amounts of helium leach through. Re ultras

Presently no, the brain computer interfaces are at least an order of magnitude less capable than they need to be for this. But the team at neuralink is making Great progress in this area and I have high hopes for the next few years.

Festo has a good product with its pneumatic muscles, but the same problems apply to them as it does to fluidic types. Complexity and the trade offs with force, frequency and range of motion. I suspect the Festo muscles will end up in mostly

You’re spot on with the harmonic drive motors. They do have good backdriving and low backlash, which is great. I certainly don’t mean to say that there is no place for electric servo motors in robots, they are fantastic for many application

It is always good to question assumptions. One you could consider is the assumption that all problems are created equal. This isn’t the case. There are fundamental and practical limits to things. For this kind of artificial muscle actuator,

Yes we’re in stealth, so there is little to be said on details. I can say that I’m a big fan of K. Eric Drexlers work and that you should read it if you want to know what the future will look like.
